+Implementation example:
+---------------
+The folder ´implementation example´ contains a notebook with a simple example of Bio2Py implementation to illustrate it´s use and applicability. 
+In this example the maximum capacity of phosphorus removal of a proposed wastewater treatment plant is evaluated. In order to do this, multiple simulations must be performed by changing the influent TP until the effluent TP is larger than the maximum value accepted by the regulatory constraints. This task is automated using the Bio2Py API.
+The corresponding BioWin simulation file can also be found on the folder.
